TFR Cells Express Functional CCR6 But It Is Dispensable for Their Development and Localization During Splenic Humoral Immune Responses

Frontiers in Immunology, 2022
Follicular T cells including T follicular helper (TFH) and T follicular regulatory (TFR) cells are essential in supporting and regulating the quality of antibody responses that develop in the germinal centre (GC).

A T follicular helper cell origin for T regulatory type 1 cells

Cellular & Molecular Immunology, 2023
AbstractChronic antigenic stimulation can trigger the differentiation of antigen-experienced CD4+ T cells into T regulatory type 1 (TR1) cells, a subset of interleukin-10-producing Treg cells that do not express FOXP3. The identities of the progenitor(s) and transcriptional regulators of this T-cell subset remain unclear. Here, we show that the peptide-

Follicular regulatory T cells inhibit the development of granzyme B–expressing follicular helper T cells [PDF]

JCI Insight, 2019
T follicular regulatory (TFR) cells are found in the germinal center (GC) response and help shape the antibody (Ab) response. However, the precise role of TFR cells in the GC is controversial. Here, we addressed TFR cell function using mice with impaired TFR cell development ( Bcl6-flox/Foxp3-cre

Follicular regulatory T cells: a novel target for immunotherapy?

Clinical & Translational Immunology, 2020
High‐affinity antibodies are produced during multiple processes in germinal centres (GCs), where follicular helper T (Tfh) cells interact closely with B cells to support B‐cell survival, differentiation and proliferation.

Proinflammatory follicular helper T cells promote immunoglobulin G secretion, suppress regulatory B cell development, and correlate with worse clinical outcomes in gastric cancer

Tumor Biology, 2017
Gastric cancer is one of the most common and aggressive malignancies. Both bacterial virulence factors and host chronic inflammation are thought to promote gastric cancer development. In this study, we investigated the potential involvement of follicular

Lymph Node Stromal Cells Generate Antigen-Specific Regulatory T Cells and Control Autoreactive T and B Cell Responses

Cell Reports, 2020
Summary: Within lymph nodes (LNs), T follicular helper (TFH) cells help B cells to produce antibodies, which can either be protective or autoreactive. Here, we demonstrate that murine LN stromal cells (LNSCs) suppress the formation of autoreactive TFH ...

Follicular Regulatory CD8 T Cells Impair the Germinal Center Response in SIV and Ex Vivo HIV Infection.

PLoS Pathogens, 2016
During chronic HIV infection, viral replication is concentrated in secondary lymphoid follicles. Cytotoxic CD8 T cells control HIV replication in extrafollicular regions, but not in the follicle.

Are Follicular Regulatory T Cells Involved in Autoimmune Diseases?

Frontiers in Immunology, 2017
In the germinal center (GC), follicular helper T (TFH) cells interact with B cells and undergo a series of GC reactions to ultimately produce high-affinity antibodies and memory plasma cells.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

B cell-T cell interplay in immune regulation: A focus on follicular regulatory T and regulatory B cell functions

Frontiers in Cell and Developmental Biology, 2022
B cells are the core components of humoral immunity. A mature B cell can serve in multiple capacities, including antibody production, antigen presentation, and regulatory functions.
